Benefits of technology

[0011]The advantages associated with the embodiments of the present invention are numerous. For example, embodiments of the present invention allow normal service items of a truck to be checked at a glance rather than requiring opening of the hood to physically check each item. Further, preferably, control logic for the real-time maintenance alert system operates independently of any existing engine protection or engine shutdow

Problems solved by technology

As such, it is sometimes undesirably time consuming to tilt the hood and physically

Embodiment Construction

[0018]Referring to FIG. 1, a system for controlling a heavy duty truck is shown. The system, generally indicated by reference numeral 10, includes an engine 12 having a plurality of cylinders, fed by fuel injectors. In a preferred embodiment, engine 12 is a compression-ignition internal combustion engine, such as a four, six, eight, twelve, sixteen or twenty-four cylinder diesel engine, or a diesel engine having any other desired number of cylinders. The fuel injectors are receiving pressurized fuel from a supply connected to one or more high or low pressure pumps (not shown) as is well known in the art. Alternatively, embodiments of the present invention may employ a plurality of unit pumps (not shown), with each pump supplying fuel to one of the injectors.

[0019]The system 10 may also include various sensors 20 for generating signals indicative of corresponding operational conditions or parameters of engine 12, the vehicle transmission (not shown), and other vehicular components. S...

Abstract

A real-time maintenance alert system and method for use in a heavy-duty truck having an engine controller with memory are provided. The system includes a sensor operative to indicate an engine condition from the group consisting of: oil filter restriction, air filter restriction, fuel filter restriction, oil level, and coolant reserve tank fluid level. Control logic at the engine controller processes the sensor signal to determine a real-time fault condition, when appropriate.

Description

TECHNICAL FIELD[0001]The present invention relates to a real-time maintenance alert system for use in a heavy-duty truck having an engine controller with memory.BACKGROUND ART[0002]In the control of fuel injection systems, electronic control units having volatile and non-volatile memory, input and output driver circuitry, and a processor capable of executing a stored instruction set are utilized to control various functions of the engine and its associated systems. A particular electronic control unit communicates with numerous sensors, actuators, and other electronic control units necessary to control various functions, which may include various aspects of fuel delivery, transmission control, or many others.[0003]In heavy-duty truck applications, in addition to utilizing a highly complex engine controller that monitors the engine conditions so that when required, engine protection and engine shutdown logic may be executed to prevent possible engine damage, some normal service items...
